I think you don't want to do that - the root filesystem you are in at that
point is *not* your normal filesystem, but the rescue root filesystem.

What you probably want to do is mount your normal root filesystem under
/mnt and fix it there.

So:
  mount -t ext2 /dev/hda1 /mnt
  cd /mnt/etc/kbd
  mv default.map bkp.default.map
    OR
  mv default.map.gz bkp.default.map.gz

That should get rid of the bad keyboard mapping; I assume without one it'll
be some sort of sane default, but if not, you'll also have to do:

  cp /mnt/usr/share/keytables/us.map.gz /mnt/etc/kbd/default.map.gz

Umounting the root filesystem is really bad... most anything you do needs
to access the disk, and if the root filesystem isn't mounted, it can't get
to it.

I'm surprised it let you do it at all.
